On: Mental speed is high until age sixty

I think it’s far more likely that certain physical ailments show up and a decreased desire for physical activity and novel experiences. Undiagnosed CFS/ME being an obvious case. I also think a lot of drug taking is self medicating for things like serotonin and dopamine dysregulation. People are trying to fill a hole, but there is a hole there.
